GRAVITY COOLING DEVICE FOR STEREOTYPE-PLATES.

Specification of Letters Patent.

Patented Aug. 1?, i915 original application filed August 9,1906, SerialNo. 329,833. Divided and this application filed October 2 1913. SerialNo. 792,984.

To all trimmit may concern Be it known that I, HENRY 'A. VVISE IVooD, acitizen of the United States, residing at New York, in the county of NewYork and have to be cooled sectional State of New York. have invented anew and useful Gravity Cooling Device for Stereotype-Plates, of whichthe following is av specification.

This invention relates to improvements in machines forcooling and.drying stereotype plates in which the latter are fed partially or whollyby gravity down an inclined plane while various operations areperformed.

In a previous application for patent on a Machine for finishing andcooling stereotype plates, filed April 6, 1906, Serial No. 310,343. Ihave described an invention on which this is an improvement.

The principal objects of this improvement are to provide means forcommencing the cooling operation at an earlier period and carrying it oncontinuously; to provide more efiicient means for rapidly cooling theplate;

to o'rovide for removing the free water from boti the inside and outsideof the plate in such a manner as to leave the printing surface in acondition sutliciently dry for immediate attachment to the press; and togenerally improve and simplify the construction of machines of thistype. i

It is to be understood that while I have illustrated and described anembodiment of the invention in which it is employed for use uponstereotype plates and While that is the principal use to which I atpresent contemplate putting it, yet the principles in volved areapplicable for operation upon other kinds of castings and articles whichor dried.

Reference is to be had to the accompanying three sheets of drawings inwhich, Figure 1 is a side elevation of a machine illustrating oneembodiment of my invention: Fig. 2 is a side elevation of a portion ofthe same on an enlarged scale, parts appearing in section: Fig. 3 is afragmentary plan of a portion of the same: Fig. 4 is a view on the line4-4 of Fig. 3: and, Fig. 5 is a sectional view on the line 5-5 of Fig.3.

In a machine of this type, a. frame a'is provided having an inclinedbody or runway a for supporting and carrying stereotype plates or thelike. The machine is intended to be used in conjunction with an arch 0in which their interior surfaces are shaved- 'From this point they passto a cooler fl and from that they move out on a table 6 from which theyare removed by hand or otherwise.

In the present case, in addition to the gen-' eral features indicated bythe reference letters. the machine is provided with a drying device fadapted to remove the free water from the surfaces of the plate after itpasses through the cooler and in addition to this, the arch c, in whichthe. shaving is performed, is provided with means for preliminarilycooling the plates while they are being shaved so as to commence thecooling earlier and thus insure the desired drop in temperature by thetime the plates reach the drying device. These features and otherprinciples-which I have employed for the purpose of improving the typeof gravity shaving machine represented in the above mentionedapplication, will now be described by reference to the constructionwhich is illustrated in the drawings. 7

The main shaft. 31 carries av worm 38 which operates a worm-wheel 39 ona shaft 26. Arranged on this shaft is a shaving blade 40 located in thearch c. The plate descends along the inclined table into this arch andis stopped in proper position therein by means of mechanism operatedfrom the shaft 26. IVhile the plate is in the arch c, it is intended tobe cooled fcnultaneously with the shaving operation. For this purposethe arch is hollow or has a channel 68, as shown in Fig. 2, this beingprovided with a supply pipe 69 at one end and a discharge r of thestereotype plate and their edges meet drying device.

When the plate reaches pipe at the other.

the arch d, it is the proper position in stopped by a gate 21*. vided toprevent spattering of water the cooler on the machine.

In the upper part of the arch d is a pipe 72 which preferably receiveswater from the pipe 70 and which is provided with perforations fordirecting the water on the top "of the stereotype plate while the latteris in the arch. In order to provide conveniently for this pipe, the archhas a channel 73 in the upper part thereof in which the pipe is located.Lower down in thearch is a plate "M-of a shapesimilar to that of thestereofrom type plate and located in such position that the plate passesover it. This plate 74: also has-a cavity 75 in which is located a pipe76 having erforations for directing the water there om against the underside of the'stereotype plate. The pipe 7 6 receives water from the pipe70. It will be seen that the water forced against the plate on bothsides will run down the same into a trough 7 7 located below from whichit discharges through a pipe 78. A second. splash guard 79 is locatedvbelow the arch d.- Whenthe cooling operation is completed, the cam foroperating the stop 21 moves into such position that the gate iswithdrawn andtheplate is allowed to feed along This drying devicecomprises a frame 80 having a series of adjustable bearings 81 supportedbys rings 82 and adjusted by thumb nuts 83. ach bearings supports aroller 84 covered by, ab sorbent gauze or other absorbent material.These rollers are cross-section that their outer surfaces form the arcof a circle of the same radius as that so that the entire surface of theplate is operated upon by therollers to remove the free water therefrom,which otherwise would damage the inking rollers of the press. The frame80 is movably mounted on the main frame a-so that the whole device canquickly removed bodily for the purpose of replacing the rollerswith. dryones to insure nearly perfect action. 1 v

For the purpose of brushing the moisture and incidental metal shavingsfrom the interior of the plate, the shaft 26 is provided with an arm 85havinga pin 86f which rotates with it. On a shaft 87 placed somewhateccentric with respect to shaft 26 is an arm 88 having a slot 89in whichthe pin 86 operates. Such a connection is required because of theeccentric relation of the shafts." Adjustably mountedwith respect tobrush:

the arm 88 is a frame 90 carrying a 91, extending the length of the;stereotype plate, adapted to be turned by the rotation of the shaft 26.so as to cleananddrythe interior surfaces of the plates.

I i-J6 fIn a machine for coolin castplates, [the combination of means go plates, means for directin passesunder the outside drying device, it .moves to a position abovethe tableover the drying and cleaning brush and can be removed therefrom by handor forced from the position over the brush by the descent by gravity. Bythe employment of the principles illustrated above, whether in the formshown or in any other form embodying these principles,it willbe seenthat the stereotype plates are fed along the machine in'a most effectiveand inexpensive manner by gravity; that the plates are cooled in a mosteffective manner by direct contact with water and are finally wiped anddried both on the inside and on the outside, hnd that the machine is"improved and simplified in manyparticulars. While I have shown anddescribed a particular form in which I at present prefer to embody myinvention, I am aware of the fact that many changes can be made thereinby any person skilled in the art without departing fromthe principles ofmy invention limited to the particular mechanism illustrated anddescribed, but

What Ido claim and desire-to secure by Letters-Patenet is for finishingand cooling cast plates, the combination of a cooling arch throughwhichthe plates pass, and a stationary splash plate located on each sideof the cooling arch. 2.
